Go in order, QSR on TURRET | Be aggressive, let guardians and walkers hit you over minions to stack berserker | Drop heal when engaging people, play careful whenever you dont have your heal up
in order again, but buy armor/counter items like debuff reducer as needed | Sell monster rounds for heroic or other items (Besides Swift) as needed | Buy Burst before escalating if they dont have too much gun dmg
Focus in insane amounts of sustain, never leave your heal unless its a teamfight to regroup. If you get jumped, dont be afraid, drop that heal and blast 'em | NEVER, AND I MEAN NEVER STOP SHOOTING
